BOOT-CRlMPING FRAME.

SPECIFICATION forming part of Letters Patent No. 377,898, dated February14, 1888.

Application filed December 13, 1887. Serial No. 257,809. (No model.)

To all whom it may concern.-

Be it known that I, EMILE HoUD, of Grafton, in the county of Worcesterand Commonwealth of Massachusetts, have invented certain new and usefulImprovements in Boot- Orimping Frames; and I do hereby declare that thefollowing is a full, clear, and exact deseription, reference being hadto the accompanying drawings and letters of reference marked thereon,forming a part of this specification, and in which- Figure 1 representsa side view of a bootcrimping frame embracing my invention as it appearswhenin use, as will be hereinafter more fully described. Fig. 2represents a rear edge View of the parts shown in Fig. 1, as will behereinafter described in full. Fig. 3 represents, upon an enlargedscale, a side view of a section of the leg part shown in Fig. 1, as willbe fully described hereinafter; and

Fig. 4 represents, also upon an enlarged scale,

a cross-section on line 00 a:, Fig. 3, looking in the direction of thearrow, same figure.

To enable those skilled in the art to which my improvements relate tomake and use my invention, I will now describe the same more in detail.

In the drawings, the parts marked A and B constitute the boot-crimpingframe of the com 'mon form, but which common form has been made in onepiece and of wood.

In myimproved crimping-frame the partA is made of wood, but the part Bis made of iron and securely fastened to thewood part A by screws 0, asfully indicated in full and dotted lines in thedrawings. A foot orbottom piece, D, also of iron, is fastened by screws E to the under sideof the foot part A of the partA.

In the ordinary and common form of crimping-frame the leather F, to formthe front of I the leg andtop of the foot' of the boot, is drawn overthe crimping-frame by means of pinchers, and the edges G of the leatherfastened to the back and bottom of each side of the frame by tacksdriven through the edges of the leather into the wooden frame, thecommon and wellknown clamp device H being employed to draw each side ofthe leather back from the instep I.

The objection to the use of tacks driven through the edges of theleather into the wooden frame is that the tacks soon puncture the woodenedges of the frame and soon split and wear the same to such an extentthat new ting the tacks, while it often happens that the workman failsto notice the failure ofsome of the tacks to hold, and the frame and itsleather are laid away to have the crimp set, and thus defective work isproduced. Still, again, the tacks become bent, and in trying to drivethem so as to hold the'leather properly the workman has to often makeseveral attempts, and

then often fails, and has to resort to new tacks. The loss of time andtacks used amount to a large item of expense. It has also been thepractice in some cases to employ crimpingframes for bootshavin gmetallioplates provided with holes or sockets, into which the tacks aredriven to secure the leather thereon, and my invention obviates, asthose skilled in the art will understand, the objections to this plan.To remedy these objections to the old frames and to save the expense andtrouble attending their use, is the object of my improvements, and, asbefore stated, I make the parts B and D of iron and dispensewith theuse'of tacks, said iron back and bottom pieces having horizontal holesbored through them to receive double-pointed steel or iron pins J, whichare held in place by set-screws K, inserted in the iron back piece, B,and bottom piece, D, as fully indicated in full and dotted lines in thedrawings. Pins J have points a a, and I pre fer to provide the ends ofthe pins, against which the edges of the leather draw, with sera quickblow of a wood mallet or wood ham- 1 mer, applied at a point above oneof the points of the pins, sets the leather down over the I point of thepin, and the operation is continued until the boot-leg front and top offoot are secured to the crimp-frame, as fully indicated in the drawings,the several points of the pins J passing through the leather, which 5 isheld in place by parts b b of the pins.

Those skilled in the art to which my invention relates will readily seeand understand the great practical advantages and benefits of my saidinvention in the manufacture of boots. The crimp-frames will last a longtime without repairs, while the crimping operation can be performed inan expeditious manner. From actual tests I estimate that with myimproved crimp-frames, as above described, a saving can Q be made of atleast eighty cents per day on each skilled crimper employed, while theactual exertion and fatigue of the operator are less than on the oldstyle of crimp frame.

When the number of boots made in a year in the United States is figuredup, a saving,

even if small, on each pair shows a very large sum in the aggregate.

Having described my improved boot-crimp frame, what I claimtherein asnew and of my invention, and desire to secure by Letters Patent is- 1.The combination, in a boot crimping frame, with the wooden parts A andA, of the metal pieces B and D, and metal-pointed pins J, permanentlysecured in said pieces, substano tially as and for the purposes setforth.

2. The combination, in a boot crimping frame, with the metal parts B andD, of the pins J, provided with points a a, holdingserrations b b, andset-screws K, substantially 5 as and for the purposes set forth.

EMILE HOUD.
